In this PMIC, you can find SOT-23 functions for your reference. The mount is attached to Surface Mount. 5 pins make up the power management. Supply voltage (Vsup) should be at least 800mV for this power management. During this IC power, the maximum supply voltage (Vsup) should not exceed 5.5V volts. There are also other types of integrated circuits included in the supervisor, like POWER SUPPLY SUPPORT CIRCUIT.
